Definitions

  • This invention is directed towards improvements in snap hinge dispensing closures for molded plastic bottles.
  • snap hinge closures of single walled construction are provided with means for positively aligning with the front of the bottle, and a relatively deeper thumb recess for facilitating lifting of a snap hinge closure lid.
  • Means are also disclosed to prevent reverse rotation of the closure once positive alignment is achieved.
  • Other disclosed features include a plug to prevent leakage of the bottle contents and means for preventing axial pivoting of the closure.
  • Plastic bottles with dispensing closures or bottle caps are the chosen packaging for a broad range of products such as shampoos, conditioners, hand lotions, household detergents, cleaning products and contact lens solutions, to list a few of a vast menagerie of products. They abound and pervade our everyday existence.
  • the dispensing closures are mounted on the neck of the bottles by inter-engaging screw threads or a snap on arrangement characterized by a frictional fit.
  • Dispensing closures are generally of single wall or double wall construction.
  • Single wall closures have one side wall of a generally cylindrical shape.
  • Double wall closures are characterized by a double sidewall arrangement having interior and exterior sidewall of generally cylindrical shape. If threaded engagement means are utilized in a double side wall closure, the threads are located upon the interior side of the interior cylindrical sidewall (see figure 7, depicting this prior art closure).
  • Double wall closures necessarily have bottle necks of reduced size, requiring a high blow ratio in bottle manufacture. This means that if a double wall closure is chosen, the volume of the bottle itself is limited.
  • single walled closures can be designed with larger necks and are thus moldable into larger sizes and shapes.
  • a closure of the foregoing type that is of lighter weight and capable of being molded with a simple mold construction.
  • the foregoing objects are attained by a snap hinge dispensing closure of single wall construction having means for providing a positive alignment of the thumb recess for facilitating the lifting of a hinged closure lid.
  • cooperating mating alignment ribs are located upon the bottle neck and on the interior of the closure.
  • the mating ribs are positioned and interrelated in such a manner that when the closure is threaded upon the bottle neck, the mating ribs do not contact one other in the first instance but eventually contact and abut each other after at least one full turn of the closure upon the bottle neck and before one and one-half full turns of the closure upon the bottle neck, thereby positioning the thumb recess in the center of the bottle face.
  • the abutment of the mating ribs provides an interference and, consequently, a stop to further threading of the closure upon the bottle neck. This stop assures the location of the thumb recess in the center of the bottle face.
  • the invention is also directed to a linerless dispensing closure able to withstand leakage independent of the application of torque.
  • the closure possesses a sealing plug which fits between the inside diameter of the sidewall of the closure and the outside diameter of the bottle neck.
  • the dispensing closure of the present invention also provides for a deeper thumb recess permitting easier opening of a hinged lid by the consumer. This is facilitated by permitting use of a bottle neck finish that are smaller at the thumb recess, thereby permitting the molding of a closure with a deeper thumb recess. This is an improvement over conventional single wall closures which are limited as to the depth of the thumb recess by the thickness of the sidewall of the closure.
  • dispensing closure of the present invention incorporates locking means for maintaining the closure in positive alignment as well as a vertical alignment means which minimizes if not prohibits vertical pivoting of the closure about its vertical* axis.
  • Figure 1 is a top plan view of the snap hinge closure of the present invention.
  • Figure 2 is a longitudinal sectional view taken along the line 2-2 of figure 1.
  • Figure 3 is an elevational sectional view of the bottle neck finish.
  • Figure 4 is a perspective view of a bottle with the snap hinge closure.
  • Figure 5 is a longitudinal sectional view taken along line
  • Figure 6 is an enlarged fragmentation perspective view of an open closure on the bottle.
  • Figure 7 depicts the prior art closure on a bottle neck.
  • the dispensing closure 20 includes a top 16, skirt 18, spout 22, cap or lid 24, thumb recess 14, and snap hinge means 26.
  • the thread means 28 shown in the drawings are interrupted, and may be of the type disclosed in U.S. Patent 4,877,144 and may also be molded in a manner disclosed therein.
  • the closure may also be molded with conventional uninterrupted threads, and any of the molding means employed in the art can be employed for such purposes.
  • the snap hinge may be of the type disclosed in U.S. Patent 4,403,702.
  • the closure further consists of an alignment rib 30 extending radially inwardly from the inner face of the skirt 18.
  • the lowermost part 30a of rib 30 terminates adjacent to or slightly above the horizontal plane formed by upper end of the thread means 28 characterized by the circumferential helix.
  • the closure also has a closure plug 32 depending downwardly from the inner face of the top 16 and extending circumferentially on and located interior of the skirt 18.
  • the plug 32 advantageously forms a seal with the interior wall of the bottle neck.
  • the closure plug 32 is dimensioned to extend for a length in the axial plane of the closure so as to fit within the aforedescribed space in order to create a barrier that will prevent leakage of the contents of the bottle when the closure is threaded upon the bottle neck.
  • the closure is additionally provided with radially inwardly extending jump threads 36 spaced circumferentially about the interior of the skirt 18.
  • the radially extending jump threads are dimensioned so that when the closure is threaded upon the bottle neck there is a clearance between the jump threads 36 and the bottle neck 18.
  • a relatively deeper thumb recess 14 upon the exterior of the skirt 18 can be provided by taking advantage of the space provided by this clearance, thereby facilitating easy opening of the closure.
  • the bottle 40 that receives closure 20 is formed with a body 42 and bottle neck 44.
  • a thread 46 upon the exterior wall of bottle neck is designed and intended to engage with the thread means 28 upon the closure 20 to fixedly engage the closure 20 and the bottle neck 44.
  • the bottle neck alignment rib 48 is positioned upon the top of the thread at a point substantially near its terminus 46a. The bottle neck alignment rib 48 extends radially outwardly from the bottle neck.
  • Molding of the closure 20 may lie in accordance with the method disclosed in the '144 patent which is advantageous because of the simplicity of the method and the simplicity of the mold construction.
  • the present invention additionally includes vertical alignment means 52 in the form of a shoulder located at the bottom of the bottle neck finish.
  • the vertical alignment means 50 extends circumferentially about the exterior of the bottle neck.
  • the alignment means 52 creates a slight clearance with the lower interior edge of the skirt 18 after riding over cam face 34. This stabilizes the bottom of the closure and minimizes the cocking of the closure.
  • the lower edge of the skirt 18 and the vertical alignment means 52 will thus abut each other when the closure 20 is threaded- upon the bottle nec_k 44. The abutment prohibits pivotal movement and assures a coaxial positioning when fully threaded upon the neck 44.
  • the bottle neck of the invention also is provided with a locking means to lock the closure into place at the point of positive alignment.
  • the locking means is shown in figure 3 as a tapered rib 54 having a tapered side 54a and a flat side 54b. Tapered side 54a of the tapered rib 54 faces in the direction which is counter to the direction of thread movement. In other words, if the closure is threaded on to the bottle neck in a clockwise direction then the tapered side faces the counterclockwise direction.
  • the rib 54 is further positioned proximate to the bottle neck alignment rib 48 on the side counter to the direction of thread movement, and is spaced apart by a distance that substantially corresponds to the width of the closure alignment rib 30.
  • closure alignment rib 30 When the closure 20 is threaded onto the bottle neck 44, the closure alignment rib 30 will contact the tapered side at a point prior to positive alignment. After riding on the tapered side 54b, the closure rib 30 snaps into position between the tapered rib 54 and the bottle neck alignment rib 48. The flat side of tapered rib 54b will now abut the closure alignment rib 30, thereby preventing reverse rotation of the closure.
